Can you swim with these underwater? Does the warranty cover water damage? How far would the bluetooth coverage go (e.g., if I left my phone at poolside, could I do laps in a 30ft long pool?) Thanks in advance!
These are “waterproof” for things like sweat/rain, not full submersion.
Bluetooth signal doesn’t go through water. 
Bluetooth at this time has a limit of about 33ft. That’s probably shorter if you’re under water. The device would probably need to be hear you for it to work.
Just got mine.
Anyone have any suggestions on how to get them to fit better or tighter in the ear canal? Even with the large bud covers they fail miserably to seat enough to block ambient sounds. I even tried using a set of covers from my corded earbuds that work great and they won’t seat/seal correctly either.
